View 2 RepliesI am having .aspx page in which there exists one textBox , label and one button. When user enter some name in textbox and then click button. The event handler of button should call function in class file(.cs). The function in .cs should retrieve value of textBox control and set it for label there. And return back.

Specifically I would like to create a static method (CreateLink) in a base class (BasePage) to automatically return the path and filename of the page called.
I code in .C# ASP.NET
private const string TEMPLATE = "~/One.aspx";
public static HyperLink CreateLink()
{
HyperLink link = new HyperLink();
link.Text = "Click here";
link.NavigateUrl = String.Format(TEMPLATE);
return link;
}
Is it possible to avoid the use of TEMPLATE hardcoded variable? Is it possible to retrieve the One.aspx path from file name and location?

I want to retrieve private (implementation and other) methods of a class which implements an interface and also is derived from (inherits) a base class.
How can I achieve this using reflection? Is there anyother way to achieve this?
This is wat m tryin to do. I need to view these private methods and their contents, I don't want to invoke them.
Dim assembly As System.Reflection.Assembly
Dim assemblyName As String assemblyName = System.IO.Path.GetFullPath("xyz.dll")

my solution currently has a website project and a class library project. I am attempting to access a session object from my class library but it is always returning null. In a settings class in my class library I store these values like so:
private static SessionProperty<WebUser> _currentUser = new SessionProperty<WebUser>("CurrentUser", delegate { return new WebUser(); });
public static WebUser CurrentUser
{
get { return _currentUser.Value; }
set { _currentUser.Value = value; }
}
I can access this just fine from any aspx page codebehind like so:
Settings.CurrentUser.User.ProviderUserKey.ToString();
However, if I attempt to do the same thing from a class in my classlibrary project it always returns null.

I have a Telerik:RadTextBox control in my markup called txtName. I'm trying to retrieve the inputed value in the code behind with foo = txtName.Text; but var and txtName always show an empty string.
Markup
<telerik:RadTextBox ID="txtName" Runat="server" Width="300px" />
CodeBehind
campaign.Name = txtName.Text.Trim();
I guess the code couldn't be easier. Basically what's happening is, when I click my 'save' button, there's a postback and the text in the RadTextBox just disappears.
update Found the problem. My web.config file had a different version of the Telerik dll file that was actually in my bin folder.

I have a listview that is retrieving some values from a database and showing them. The information are; product name, price, etc. At the end of each row, I have a textbox and a button. Within the textbox the user is able to insert how many items he wants of that particular item and by clicking the button I want the value from the textbox retrieved. It may be relevant to mention that
with the button is a event attached (OnClick) which is where I want the value of the textbox to be retrieved. The part that is giving me problem is retrieving the textbox value for that specific row when the button is clicked.

I'm working on a multipage form in .Net using AJAX (UpdatePanels). I am stuck right now trying to get a class added to the textbox that is invalid to basically highlight it red.
I found a sample online using this code:
$("span.invalid").bind("DOMAttrModified propertychange", function (e) {
// Exit early if IE because it throws this event lots more
if (e.originalEvent.propertyName && e.originalEvent.propertyName != "isvalid") return;
var controlToValidate = $("#" + this.controltovalidate);
var validators = controlToValidate.attr("Validators");
if (validators == null) return;
var isValid = true;
$(validators).each(function () {
if (this.isvalid !== true) {
isValid = false;
}
});
if (isValid) {
controlToValidate.removeClass("invalid");
} else {
controlToValidate.addClass("invalid");
}
});
That works perfectly, in IE only. For some reason this code does not ever fire in Firefox. I've looked up the DOMAttrModified event and it sounds like this should work in Firefox, hence it being in the code. I must be missing something though because it does not work.
I'm open to other solutions for what I am trying to accomplish here if anyone has something good. Basically the form is 3 pages right now. Page 1 has a variable number of fields that require validation. It could be 5, or 13 fields, based on a checkbox. Page 2 has another set of fields that need to be validated separately. Obviously when I am on page 1 it should not try to validate page 2, and vice versa.
I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.
if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.

In the example below I have set the control style to 'controlName' I want to use this class to define what my textbox looks like in edit mode. This works ok, so far so good. The Problem In a button event I add the class "validationError" to this textbox if the data is incorrect. When the grid gets rendered I expect to get 'controlName validationError as the class applied to the textbox. Unfortunately, it seems that the declarative statement overrides this and simply ends up as 'controlName' how I can intercept the application of the declarative class so that I get what I desire here?
<asp:BoundField
DataField="Name"
HeaderStyle-CssClass="headerName"
ItemStyle-
CssClass="itemName"
ControlStyle-CssClass="controlName"
HeaderText="Name"
